SPECIFICATION forming part of Letters Patent No. 605,895, dated June 21, 1898. Application died September 10, 1897. Serial No. 651,194. (No model.)

T @ZZ wiz/0711, it may concern.-

Beit known that I, CHARLES T. MURRAY, of

Kansas City, Jackson county, Missouri, haveV v features of construction and combinations of parts, as will be hereinafter described and claimed.

The object of the invention is to produce a generator of the character above mentioned which'is of knockdown and portable construction, so that its parts may be easily and.

quickly assembled together in operative relation to a stereotype-table, and which is simple, strong, durable, and comparatively inexpensive of construction.

In order that the invention may be fully understood, I will proceed to describe it with reference to the accompanyingr drawings, lin whichj Figure 1 represents a vertical central section of a steam-generator embodying my invention and also shows in elevation a portion of a stereotype-table of the customary construction. Fig. 2 is a horizontal section taken on the line II II of Fig. l.- Fig. 3 is a horizontal section of the mixing-chamber and aircontrolling-valve mechanism. Fig. 4 is a vertical section taken on the line IV IV of Fig. 3.

In the said drawings, l designates a cylinder, preferably of sheet metal. 2 designates a circular base-plate upon which said cylinder rests and by which it is embraced.

3 designates a circular top plate closing the upper end of the cylinder.

4 designates a cylinder or tube which is arranged centrally of the cylinder l and .is screwed at its lower end into a cap 5, occupying a hole in thebottom plate 2, and provided with a horizontal flange or shoulder a, which rests upon said bottom plate and thereby supports the tube 4. Screwed upon and closing the upper end of said tube is a cap 6, and said lsurrounds the tube 4.

cap tits snugly in an opening inthe top plate 3 and is provided with a shoulder or flange 6, which ,bears against the under side of said top plate and thereby is held reliably in position. The bottom and top plates 2 and 3, respectively, are clamped firmly against the opposite ends of the cylinder 1 by means of tiebolts '7 and nuts 8, engaging their opposite ends, as shown.

In-order that the water contained in the generating-tube 4 may be more quickly converted into steam, said tube is provided with a plurality of U-shaped pipes 9, which communicate attheir ends, in different horizontal planes preferably, with the tube 4, in order to provide numerous passages through which the water maycirculate and becauseoi.' .being thus divided or segregated be more quickly raised in temperature.

10 designates an outlet-pipe for the steam. It communicates with the upper end of the tube 4 through the cap 6 preferably, and at its upper end with one chamber or compartment of the stereotype-table. A second outlet-pipe ll also communicates with the upper end of the tube 4, and at itsupper end communicates with the second chamber or compartment of the stereotype-table. Y

l2 designates the return-pipes for the steam orcondensation thereof. These pipes communicate at their upper ends with the chambers or compartments of the table hereinbefore referred to and at their lower ends communicate with the generating-tube 4, just above the burner, in order that the temperature of the water returning through said pipes may be more quickly raised.

I 13 designates a gage of thecustomary construction Which communicates at its upper end with the pipell' and at its lower end with one of the pipes l2; v

. 14 designates an annular pan or trough whereinthe combustible mixture of gas and air is contained. Said annular pan or trough rests upon the bottom plate Qand lsnugly It is provided with a burner-cap 15, provided with a largenumber oi' burner-openings16,` from whichthe flame shoots upward and impinges uponand .envelops the return-pipes l2 and the pipes 9 of IOO the generating-tube 4. At one side the pan or trough is provided with a tubular offset 17, and tting upon the same and projecting through the cylinder 1 is a tube 18, which in practice is the mixing-chamber of the device.

19 designates an approximately hemispherical perforated cap which is secured at the outer end of the mixing-chamber, and 2O designates a valve-casing which extends longitudinally of and projects centrally through said cap and into the mixing-chamber. At

its inner end said casing terminates in the the similarly-formed cap 1S) and is provided at intervals with openings 25, which may be caused, by the proper adjustment of the 1 draft-regulating cap, to expose more or less of the openings of the cap 19 and thereby permit of an increased or diminished volume of air passing` into the mixing-chamber.

In practice after the generator is properly assembled with relation to the stereotypetable, as shown in Fig. 1, and is supplied with the proper quantity of Water the valve 22 is manipulated to permit of the passage of gas under pressure through the mixingchamber and into the pan or trough 14. The cap 24 is also manipulated to expose more or less of the openings of the cap 19 in order that the suctional action exerted by the discharge of the gas into and through the mixing-chamber may draw a sufficient volume of air into [the mixing-'chamber and thence into the pan or trough 14, by which time the gas and air are thoroughly commingled and are in the nature of a combustible gas, which escapes through the burnercap 15 and is ignited by the introduction of a lighted match or taper through a dooropening 26, formed in the cylinder 1, and closed normally by a sliding plate 27. The iiame and heat from this circularburnercap envelop and impinge partly upon the tube 4 and pipes 9, and as a consequence the water is quickly generated into steam, which escapes by way of the pipes 10 and 11 to the stereotype-table and returnswith its temperl ature lowered or as condensed steam back to the genei'atingtube by way of the pipes 12, as will be readily understood. This circulation is continuous as long as the burner is in operation and water is contained within the tube.

The flame and heat of course maybe regulated by the volume of gas and air and by the quality of the gas, determined, of course, by properly proportioning the volume of each discharged or admitted into the mixing-chamber.

If it is desired to move the generator indej pendent of the table, it is only necessary to uncouple the pipes 10, 11, and 12 from the table, and if it is desirable to ship the generator it may be done with the parts in operative position, because it is of compact construction, or by removing the pipes 10, 11,

and 12 and the nuts 8 from the upper ends of the tie-rods the generator may be quickly and easily taken apart.

From the above description it will be apparent that I have produced a steamgener ator for stereotype-tables which embodies the features of advantage enumerated in the statement of invention, and it is to be under stood, of course, that changes which do not struction involved may be resorted to.

Having thus described the invention, what I claim as new, and desire to secure by Letters l Patent, is-

1. A steam-generator, comprising a cylinder, a top and a bottom plate clamped thereon, a cap stepped into the bottom plate, a cap stepped into the top plate, a generating-tube screwed into and closed by` said caps and arranged centrally of the cylinder, pipes comm unicating with said tube and projecting laterally therefrom, out-let and inlet pipes comi municating with the upper and lower end of the tube, respectively, and a burner surl rounding said tube and resting upon the bottom plate of the cylinder, substantially as` described.

stepped into the top plate, a generating-tube 2. A steam-generator, comprising a cylinder, a top and a'bottoin plate clamped thereon, a cap stepped into the bottom plate, a cap l screwed into and closed by said caps and ar- 1 ranged centrally of the cylinder, pipes communicating with said tube and projecting latburner, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.
